Duly noted. I should have written, “not just ‘depends’, but also…”.

Adam, conflicts are dependencies.

@Mikko, the main goal of debgraph is to provide a powerful API for querying any sort of information about package relationships, as Daniel noted — not just dependencies, but also “provides”, “conflicts”, and others. We tried not to make assumptions about how it will be used. Hopefully it will become a solid launching pad for people interested in analyzing the package database to look for interesting constellations.

@Obey, thank you very much for giving a talk about our projects at FOSDEM. I wish that I could be there to meet you and enjoy the talk.

Regarding my work on debgraph being “unused”: Robert Lemmen and I are working behind the scenes to replace the old (pre-SoC) debgraph so that its analysis results can be used by the community. The new data will be published on his website at http://debian.semistable.com/debgraph.out.html (or similar) when it’s ready. Everyone is free to download the code and do her own analysis, but we will be publishing nightly analyses of (e.g.) dependency cycles to the web for convenience. If there are other analysis results that are helpful to many community members, we are happy to include nightly snapshots of those as well.

I will be updating my SoC blog as our work (and my Debian involvement) progresses.

Cheers!

@nion Well, I didn’t hear your reasoning well enough I think. Then again I may have had one too many beers. Anyway, I’m not going to dig past what persons involved want to reveal. It would only be to the extent that it would be useful for future GSoCs.

“There’s no nothing. Nico, what happened ? And obviously, he’s still developing for Debian.”
I had good reasons not to continue on summer of code, if you want to know the details ask our mentors, I won’t post them in public.
(Didn’t we talk about the SoC and my reasoning at the OMGWTFBBQ?)
cheers

Mikko, as I understand it, the debgraph project was about creating a (virtual?) graph of the whole database, and giving the user some sort of language to describe queries about relationships between package. aptitude has a few dependency graph-basd searches, but nothing very sophisticated. Presumably debgraph provides more.

About debgraph: I thought that aptitude already computed dependencies? How is this different?

I’m looking forward to hear more about Aptitude-gtk and Lintian process. The Ultimate Debian database project seems interesting, too.

I myself was really curious about this GSOC results and found pain in having to search in too many different channels to find this info. The Debian wiki’s, which is supposed to track such things, were created but abandoned. For that reason, thanks for these efforts.
